Abstract
A waterproof structure including an extension shaft disposed at an upper side of a vertically extending ball screw spline shaft so as to be coaxial with the ball screw spline shaft, a cylindrical cover member that covers the extension shaft and the ball screw spline shaft and is configured to be extended and shortened in a direction along a longitudinal axis of the extension shaft, and a rotary connection unit that connects the ball screw spline shaft and the extension shaft to each other so that the ball screw spline shaft and the extension shaft are configured to rotate relative to each other around the longitudinal axis, where an upper end of the cover member is fixed to an upper end of the extension shaft.
